SanDisk Cruzer will not launch Secure Access from USB 3 slot

SanDisk Cruzer will not launch “Secure Access” from USB 3 slot. (ERROR: Please run SanDisk Secure Access from a SanDisk external device.) Worked fine on USB 2 slot. BIG problem with so many new computers coming with USB 3 slots…

Can the Cruzer be used on a USB 3 slot? If so, how?

Thanks, Brad
